GAFGLAS®
STRATAVENT® Eliminator™ Base Sheets
Description
GAFGLAS STRATAVENT Base Sheets are premium-grade roofing felts constructed
around strong glass fiber mats and high quality asphalt. The bottom of
the sheet is granule-surfaced to provide positive venting of any trapped
gases under the roof membrane.
STRATAVENT Base Sheets are available for nailable and nonnailable substrates.
GAFGLAS STRATAVENT Nailable Base Sheet is mechanically attached to wood,
structural wood fiber, poured gypsum, and lightweight insulating concrete
decks. GAFGLAS STRATAVENT Perforated Base Sheet is unique in the industry:
its patent pending perforated design allows mopping asphalt to flow through
to the substrate as the next ply of the roof system is installed. The flow-through
asphalt uniformly bonds the STRATAVENT Perforated Base Sheet and the subsequent
roof
system to the substrate.
Uses
GAFGLAS STRATAVENT Base Sheets are venting base sheets designed to
be used in various GAFGLAS built-up and RUBEROID® modified bitumen
roofing systems. They can be used over both nailable and non-nailable substrates,
including certain existing old roof surfaces and isocyanurate foams.
